What is a "DHTML page" here?

In Zope you have "DTML Methods" and "DTML Documents". Both are
OBJECTS, not PAGES.

Ah. Sorry. Many years with development of other systems left me using the wrong grammar. The 'page' would be what I'd hoped to display in a browser when I pointed it at my domain name.

Zope is *not* PHP nor ASP not ..., it's an object-oriented
application server used to PUBLISH objects on the web.
Please read the Zope Book (Zope3 version available at
<http://www.zope.org/DevHome/Wikis/DevSite/Projects/ComponentArchitecture/FrontPage/Zope3Book >),
then came again if you have any questions.

Ok, so, after starting with the book, one of the first things it says is..

Zope 3 has very flexible skinning support, which allows you to alter the look and, to some extend, the feel of the ZMI. You can reach other skins by using the ++skin++ URL namespace. One nice skin is ZopeTop, which is excluded from the Zope X3 3.0.0 release but available in the repository. To see the initial contents screen of the ZopeTop skin, as shown in Figure 2, you use http://localhost:8080/++skin++ZopeTop/manage.

So, I tried to go to that page, and I got the following in my logs...
